calcium level

[mike90]

hi all.
just tested my calcium level today. according to my test kit (it's a hagen, i know not the best) it says my calcium is about 440. the kit itself says calcium should be anywhere from 400 to 440. is this true? what is a good level to keep calcium at?

thanks.

I aim to have a stable CA/ALK level. I like 450ppm to 4 meg/l of alk
